ther'object isto provide means for augment:

ing radiation of heat from the container and O furthermore, to prevent,the wasteful flow of lubricant when steam is shut off the chamber towhich the device is applied.

Other and further objects andadvantages of the invention'will appearfrom the followingdescription taken in connection with the accompanyingdrawings,- in which Fig. 1 is a central vertical section showing theinvention; p Fig. 2 is a top or plan view; and

fication of a detail.

The device consists of a body portion 10 provided at its lower end witha securing nipple 11 and an angular portion 12 for the engagement of awrench for attaching the nipple 'to its support in the usual manner. Adome shaped cap 16 removably secured to the body portionlO forms aclosure for the chamber or lubricant container 17.

A tube 13 extendingaxially' through the container 17 is provided with aspring closed valve 14:. The valve is held in operative position and isenclosed in a valve chamber formed by the cap 15 which is threaded tothe tube. A hole 26 in cap 15 completes a passage from the tube 13 tothe chamber 17 The body portion 10 is preferably provided with radiatingribs 18 for cooling said container. The body portion may, if desired, be

m provided with a pet-cock 19 secured to a passage leading'from' thebottom of chamber 17 for removing the water. of condensation as occasionmay require.

The device is shown secured to a steam chest 20 in which numeral 21designates a steam passage which communicates with tube 13. p

The operation of the device is as follows:

r The chamber 17 being filled with lubricant 0 such as grease, and cap16 replaced, the de- Fig. 3 is a vertical section showing a modivice'is-ready--;for service. Steam entering the passage-'21 will pass uptube 13 raising valve 14' and continue through passage 26 into chamber17. If the container is filled with grease it will immediately melt andbecome a liquid. When the pressure inchamber 17 equalizes the pressurein the tube the valve will drop and close the passage. Condensation nowtakes place in chamber 17,'the lubricant being lighter than the water ofcondensation'will float and be forced into the valve chamber. Therecession of temperature and pressure in chamber 17 will again cause thelifting of the valve and a small quantity of lubricant spreading out asa film'on the 3 walls of the tube will pass down the tube at eachimpulse. Should steam be shut off from the chest 20 the valve 14: willcease its impulse and stay closed, preventing further flow of lubricantuntil the steam is let on again.

In the modification shown in Fig. 3 the tube 130 in threaded to the bodyportion 10 and a ball'valve 140 is seated at the throat of the tube. Achamber 22 near the top of the tube is filled with fibrous material suchas cotton wick which may be compressed to any desirable degree by ascrew 23 having a small passage 24. Tube 130 also is contracted at 25below chamber 22.

The fibrous material forms a further impediment to the passage of matterthrough tube 13 which will result in slower but somewhat similaroperation of valve 140 to that shown in Fig. 1.

What I claim as my invention and desire b to secure by Letters Patent,is

1. In a lubricating device, in combination, a lubricant'container, asteam chamber, a pasbetween the container and steam cham- )0 her, saidpassage comprising a tube extending upwardly within said container, aspring pressed valve closing the'upper end of said passage when thepressure within said container and chamber are equalized, said valvebeing adapted to be moved by the steam pressure to, open said passagewhen the pressure in saidchamber exceeds that in said container, and acap within said container threaded ,on the upper end of said tube forenclosing said valve and for positioning the same on the upper end ofsaid passage. 7

2. A lubricating device comprising a container provided with a threadednipple extending outwardly therefrom and a tube extending upwardlytherein, said tube and nipple being provided with a bore, a springpressed valve for-closing the upper end of said bore, a cap forenclosing said valve, said v cap having an aperture through its sidewall,

a closure for said container for enclosing said tube, cap and valve, apet cock in'communication withthe lower portion of said container, andheat radiat ng ribs on the exterior of said container.
